Abstract

The incorporation of hydrogen into strained InxGa1−xAs/GaAs quantum wells results in the formation of shallow, H‐related radiative states which compete with, and quench, the intrinsic band‐to‐band luminescence. By comparing the photoluminescence data obtained from hydrogenated material with secondary ion mass spectroscopy profiles from deuterated material, it is possible to deduce that the H‐related radiative states are associated with H which is accumulated at the well interfaces.
